NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 295,911, dated April 1, 1884.

Application filed February 11, 1884. (No model.)

To all whom) it may concern.- I

Be it known'that I, GEORGE O. DITZLER, of Union Station, in the county of Wells and State of Indiana, have invented certain new and useful Improvements in Nut-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in nut-locks; and it consists in certain features of construction and in combination of parts, hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is aviewin perspective of my improved nutlock as applied to fish-plates on a railroadtrack. Fig. 2 is a side elevation of the nut lock, showing the manner of unlocking the nuts. Fig. 3 is a plan view of the two pieces comprising the lock. Fig. 4 is a side elevation of the nut-1ock in looking position.-

. The nut-lock consists of the two pieces A and B, made of thin elastic plates of metal. The former is slotted at one end to embrace the bolt under the nut, and has an opening, a, through which the tongue I) of the part B passes. This tongue is bent or offset in the form shown in Figs. 2 and 4, and extends a short distance under the plate A, as shown, and forms a lever with the fulcrum at the opening a, by means of which the plate A is raised to the position shown in Fig. 2 for unlocking the nuts.

In applying the nut-lock, the part A is placed under the nut G, with the slot a emv bracing the bolt, and by means of the slot is position. This part B is of such length that,

when moved toward the nut D as far as the interlocking of the parts at a will permit, the broad end of the plate B will butt against the nut O. The elasticity of the parts A and B will hold them in the position shown in Figs. 1 and 4, in which the nuts are securely locked. By raising the part B, the nut-lock may be brought to the position shown in Fig. 2,thereby releasing the nuts, so that they may be loosened or tightened, as required.

This nut-lock is simple, inexpensive, convenient, and effective, and Well adapted to secure the nuts or fish-plates used on railroads.

What I claim is- A nut-lock consisting of the parts A and B,

i the former provided .with the orifice a and the The nut O is slotted end a, and the latter provided with r the tongue b, offset in the manner shown, and adapted to engage the orifice a, and the two parts applied and operated as described.

In testimony whereof I sign this specification, in the presence of two witnesses, this 2d day February, 1884.

GEORGE C. DITZLER.
